Sharp GR8 vs Hisense U7Q

Sharp GR8 in its promotional materials boasts of "very high brightness" at a level of 500 nits. Unfortunately, our tests showed that the reality is somewhat different – the average luminance value we managed to achieve was around 360 nits. This is rather an average result, especially in the context of the manufacturer's claims. Such brightness does not allow for a full enjoyment of HDR effects. The image is a bit more defined than in standard SDR, but it is difficult to speak of true richness and depth in bright elements here. However, praise is due for the DCI-P3 colour gamut coverage at a level of 95%. This is a result of the application of an additional PFS layer, known from QLED technology. As a result, the colours are vivid and have a pleasant, natural tone, which somewhat compensates for the deficiencies in brightness.

Since the algorithms responsible for blacks are performing quite well, we expected a similarly good effect regarding brightness and overall HDR quality. Unfortunately – here we have to disappoint you a bit.

The U7Q is a sufficiently bright television – under the best conditions, it can achieve around 800 nits, which indeed impresses on some scenes, especially in scenes like those from the film The Meg. Bright areas can shine, and the HDR effect is noticeable. The problem arises when there are very small, bright elements on a dark background – for example, in Sicario 2 or in the second scene from the film Life of Pi. In such moments, the dimming algorithms work too aggressively. Yes, the blacks look great then, but the brightest points can almost completely disappear, causing the HDR effect to vanish and the details to be barely visible. It's just the nature of this technology in this price segment.

As a consolation, it's worth mentioning that the U7Q is marketed as QLED (in practice, a PFS layer is used, which works very similarly), and it is indeed capable of displaying a wide colour palette – a DCI-P3 coverage of around 94% is a very good result for this class.

At the outset, it is worth noting that colour reproduction tests are always conducted in the best factory picture mode. In the case of Sharp GR8, this is the “Film” mode. As for white balance, which affects how we perceive colours on the screen, in SDR mode, there is an immediate noticeable dominance of blue. This results in an unnatural cooling of the image – blue elements take on a purple hue, and skin tones acquire a pinkish glow, as we can see in the comparative photo from the film STAR WARS. During the Color Checker test, it was clear that the colour samples deviated from the reference values, confirming considerable errors in colour reproduction. The gamma was also not ideal – it caused excessive brightness throughout the entire image, resulting in a lack of depth and appropriate tonal transitions in the scene.

In 4K HDR mode, the situation looks significantly better. The dominance of blue is much less noticeable, although there are minor issues with the combination of red and blue. This causes some shades to appear somewhat unnatural. The EOTF curve, responsible for the brightness of the image in 4K HDR content, revealed another problem – the television tends to excessively dim the image across the entire surface of the screen.

In summary, the “Film” mode in Sharp GR8 would require a few adjustments to fully utilise the potential of this television. Fortunately, we took care of that and proceeded with calibration.

We tested the U7Q in the best possible picture mode, which is Filmmaker Mode. This is the mode that is supposed to provide the most "filmic" and creator-intended experience – right out of the box. Unfortunately… even this professionally sounding name does not guarantee a perfect picture.

In our unit, the problem lay in the incorrectly set white balance. Both in HD and 4K content, the picture had too much blue and red, which caused the screen to take on a slightly rosy tint. It didn't look terrible, but it was noticeable – especially in bright scenes and white backgrounds. This alone could perhaps be forgiven, but the biggest problem is managing brightness in HDR content. The EOTF curve from measurements confirms what we saw earlier during scene tests: the television can overly darken the smallest bright elements, causing them to nearly disappear, or on the contrary – excessively brighten the brightest ones, which affects the naturalness of the picture.

Sharp GR8 is one of those televisions that truly gains a second life after proper calibration. Both in HD and 4K content, the white balance performs very well, especially when considering the price segment of this model. The image becomes much more aligned with what the director intended to show – colours look natural, and skin tones acquire the appropriate depth and warmth. The brightness characteristics also make a very positive impression. Both gamma and the EOTF curve display really solid values. While minor imperfections can be noticed, they are subtle enough that they are difficult to detect during everyday viewing. In summary, calibration allows the Sharp GR8 to showcase its best features, offering an image that is not only pleasant to the eye but also faithfully reflects the creators' intentions.

Thanks to specialised tools, we managed to correct the colour quality in SDR content to nearly perfection. In materials with lower dynamic range, the delta E errors dropped below 0.5, which can be regarded as an almost reference result. The picture on television, YouTube, or classic Full HD looks really very good after calibration. Alright – but where did we not manage to improve the image so easily? Primarily, it concerns HDR quality content. Although we managed to somewhat 'tame' the white balance and eliminate pink tints in most scenes, unfortunately, we no longer had full control over brightness management. We set the local dimming settings according to the best observations – SDR: Medium, HDR: High – but the U7Q still did everything a bit its own way. There were still cases of excessive dimming or brightening of details that calibration simply could not eliminate. And although the overall reception of the content is significantly better, one must reckon that the U7Q will always have something to say at the end with an 'but'.

Sharp GR8 has been equipped with the "10-bit colour reproduction" feature, which theoretically should improve the smoothness of tonal transitions. In practice… well, the effect is surprising, but not in a particularly positive way. Even at the highest settings, it is difficult to notice any impact on the actual tonal transitions. Instead, the feature surprisingly smooths out what it shouldn't – walls, shirts, or other flat surfaces look almost like they have been freshly ironed. In the test, we had to note that there is simply no actual impact on tonal transitions.

As for image scaling, here Sharp GR8 performs significantly better. The television can give the image a plastic, smooth characteristic, meaning even lower resolution content looks quite good. Of course, with more demanding details, such as thin tree branches in the background, one can notice slight jaggedness, but it is not something that would significantly affect viewing comfort.

There are situations where we would like to smooth out tonal transitions a bit, especially in older materials – those with limited source quality. The U7Q is equipped with a feature called "Smooth and Gradient Image," but unfortunately... it works very poorly. In the "Low" option, the effects are practically unnoticeable, and other settings smooth details but do not improve tonal transitions. The only positive aspect is that the feature does not interfere with film grain, so it does not ruin the natural structure of the image.

Fortunately, upscaling content performs quite well. The image is not excessively sharpened, and there is no artificial clarity – and although it is known that this is not the level of high-end televisions, the U7Q handles displaying really old content in a completely acceptable manner without any issues.

This is where Sharp GR8 has the chance to stand out from the competition in its price segment. The television is equipped with a 144 Hz refresh rate panel, which is an impressive achievement, especially if we plan to use it for dynamic content such as action films, sports broadcasts, or video games. Additionally, the manufacturer has ensured the presence of motion smoothing technology, commonly referred to as a “smoothness enhancer.” The user has three levels of adjustment at their disposal, allowing them to tailor the effect to their own preferences – from subtle smoothing to a more aggressive intervention in the smoothness of the image. This is a nice addition, particularly for those who mainly watch films and care about smooth, cinematic sequences without irritating stutters or frame drops.

U7Q is indeed a very fast television, just like its more powerful version "PRO". At a resolution of 4K, it supports up to 144 Hz refresh rate, and if someone wants even more – in Full HD, you can achieve up to 240 Hz! This will mainly benefit PC gamers, but it is worth appreciating – it is a rarely seen feature in this price segment. Right from the start, it is clear that the U7Q has been designed with dynamic content in mind, such as games or sport. In films, we are not left "out in the cold" either – the U7Q offers an "Ultra Motion Smoothness" feature, where using two sliders you can adjust whether you prefer a smoother, theatrical image or something closer to a cinematic style with a visible film frame. It is good that, as with most manufacturers, we have a choice here as well and can adjust it to our own preferences.

If the television has a 144 Hz panel and two full HDMI 2.1 ports, it is clear that it has been designed with gamers in mind. The Sharp GR8 offers exactly that – high refresh rates and the appropriate connections that will allow you to get the most out of modern consoles and PCs. It also features ALLM, which automatically switches the television to low latency mode, and VRR, which ensures the image does not stutter even during more demanding moments. In practice, everything works as it should, and it is hard to find fault with anything. However, there are some shortcomings. It lacks support for HGiG, which is a feature that better adjusts HDR for games, as well as Game Bar, which makes it easier to quickly adjust settings without leaving the game. Despite these drawbacks, the Sharp GR8 is truly a solid option for gamers.

The Hisense U7Q is a television designed with gamers in mind – and this is immediately evident from its gaming capabilities. It has practically everything you could wish for: variable refresh rate (VRR) – check, automatic game mode (ALLM) – check, and on top of that, high refresh rates of up to 240 Hz in Full HD and support for various resolutions, not just 4K. This is truly a great set of features that makes the U7Q perform well both in fast-paced first-person shooters on consoles and in more demanding titles on PC. Of course – as with most Hisense models – there is a lack of proper implementation of the HGiG feature. It's a shame because HGiG allows console brightness to be matched to a specific television, which in practice makes displaying HDR games according to the creators' intent much easier. Without this, you simply have to reckon with certain limitations in the final HDR image in games.
